The scrolling problem isn't with just Firefox, it's with internet explorer and every thing on the computer. I can't even scroll on image viewer to make a picture bigger. My mouse stopped working as of two days ago without warning. It's either windows or an update or something like that.

In such a case you need to click outside the plugin to make scrolling work once again.

Unfortunately it was the 24th out of 30 add-ons so I had a bit to go through. It's called 'smoothwheel' and it worked well but they must have ungraded it, or I messed up some option and it stopped working on anything of a graphic nature. It worked fine on text.
</p><p>I really didn't want to go through those add-ons one at a time. I was hoping there might have been an easier way, but that's life... there isn't always an 'easier way'.

</p>If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions)2013-05-21T11:08:33-07:00cor-elhttps://support.mozilla.org/ga-IE/questions/959983#answer-438548<p>If it works in Safe Mode and in normal mode with all extensions (Tools &gt; Add-ons &gt; Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
